55% x n = 33
divide 33 by .55
n = 60
Answer:
(a) T = 16√x
Step-by-step explanation:
T is directly proportional to √x, so we can say,
T=k√x (where k is a constant)
now, according to the question,
400=k×√625
400=k×25
k=16
so, putting the value of k in the equation, T=16√x

We know the bottom triangle is a 45, 45, 90 triangle, so the hypotenuse is √2 times the value of the legs:
(√2)(√2)
=√4
=2
Now, we can use this to solve for y. The top triangle is a 30, 60, 90 triangle. The side we found above is the side across from the 30 degree angle. The side opposite the 60 degree angle is √3 times the side across the 30 degree angle. Therefore, we can solve for y by multiplying 2 by √3
y=2√3
Look to the number to the right of the place you're rounding. Rounding to the thousandths, look to the ten thousandths place and if the number Is 5 or greater, round the thousandths place up. 4 or less, round down. For your number, ten thousandths place is 9 so the thousandths place is rounded up.
